Add TS support to @babel/parser's Scope (#9766)
* [parser] Allow plugins to extend ScopeHandler

* Directly extend Scope

* Don't use new.target to get the ScopeHandler

* [parser] Add TS enum  support to the Scope

* Remove duplicated options in tests

* Fix

* Fix flow

* Rename tests

* Add tests

* Full typescript support in scope

* Remove BIND_SIMPLE_CATCH

SCOPE_SIMPLE_CATCH was used instead

* Export TS types

* Register function declarations

* Fix body-less functions and namespaces

1) Move this.scope.exit() for functions from parseFunctionBody to the callers.
    Otherwise the scope of body-less functions was never closed.
    Also, it is easier to track scope.exit() if it is near to scope.enter()
2) Register namespace ids for export

* Disallow redeclaration of enum with const enum

Use for..of Object.keys instead of for..in (#9518)
In https://github.com/babel/babel/issues/9511 (and #9495 is another symptom), @PavelKastornyy reported a node crash becaue the JavaScript heap run out of memory. The problem was that their code was adding enumerable properties to `Object.prototype`: it is something that shouldn't be done, but Babel shouldn't make node crash if someone adds them.
I reduced down the problem to `for...in` loops in `@babel/traverse` that grew the memory consumption exponentially because of that unexpected properties.
